Which 140 class .284 bullet?

[MuleyFever]

I'm looking at trying a 140 class load in my 280AI. 143 Hammer Hunter, 145 Barnes LRX, 140 Nosler AB?

Opinions?

I'm a Nosler fan, so I pick Partitions and Accubonds. However, I use 160 grain Accubonds and Partitions in my 7 SAUM.

I killed a couple deer and an elk with a 139lrx, started 3180. No fuss.

Slightly heavier, but the Swift Scirroco 2 150's are wicked in my wife's 7X57 at 2800fps.

If you are set on using a 140 class, then go with the one with a higher BC. Eld-x.
But the 280ai is such a great rifle, go heavier, you will not regret it. I started with the 175 but went with the 180. The 140 leaves a little faster but at around 4-500 yards the 180 is moving faster and with a higher amount of energy. And as you go to 600 and beyond, the velocity spread is even more.
I live in Northern Utah and would be happy to help with your load development.

Partition or a-frame.

So I would not go light on the Eld-X. I may try the 175 later though. Right now I am trying to see what my Kimber likes. Many people suggest the thin barrel like on a Kimber may like the lighter bullets. I am working with the 160 AB now and want to try something in the 140's next. I don't plan to shoot much over 500 max so I really don't need the 175's. A 140 will kill anything plenty dead at that distance.

I am leaning to the Hammer. They claim their design is less sensitive to seating depth and my mag length is quite a bit shorter than my chamber allows so I am about .085 off the lands.

I don't chase lands in any of my rifles. I only worry about loading them to mag length. My 7 SAUM, for instance, I load to 2.815" with the 160 grain Accubonds. I'm getting 2950fps out of my 22" factory barrel in my Remington Model Seven SS rifle.

I’m not familiar with the hammer, I will look into that.

You could split the distance and go with a 150 grain Accubond. Or 150 grain scenar or ELDX

I load the Hammer in a couple 280 AI's and 28 Nos. excellent bullet. load development was the easiest I have ever had. i use H4831sc and cci 250's in the 280 AI's

I've tried a few different loads. 162 ELD-X, 160 partition, 160 accubond, 140 accubond, 140 etip, and the 143 Hammer Hunter. Mine really liked the 162 ELD-X the most - right at 0.5". The 160 partion and 160 accubond shot good as well, 0.75". The 140 accubonds and etips were around an inch. I have had inconsistent groups with my 143 hammer loads. Some are awesome, some not so much. Haven't figured that out yet. But so far none of the bullets I've tried have been bad.

Not to derail your thread, but I also have been looking at the hammers. For the 6.5 creedmoor and my 6.5 x 284.
They intrigue me. Seem to have great reviews and I like the concept.

New to the forum here, but I am really happy with 140gr AB out of my 280 AI for muleys and white tails.

140 gr. Accubond, Partition, or E-tip would serve you well for anything you would likely hunt. I have tested all three of these bulets in different rifles of mine by shooting them into gallon water jugs lined up from 25-100-200-300-400- & 500 yards. I tested expansion, penetration, and weight retention. I can say with confidence that all three are great bullets. There's been a lot of these bullets used on game also with great results.

I was using the 140 gr. Partition in my 280 AI but last year I switched to 140 gr. Accubonds. They have worked very well for me and were easy to find a load for. I used ONE of those on my grizzly bear this fall! One shot at 158 yards and he went nowhere. Penetration, expansion, and all of the above was great.

I'm using IMR7828SSC for my load but there are a lot of other good powders that would work just as well.

I'm using the same powder. I may just order a sample pack and try it. How much jump do you have on the 280ai load?

 

[Zzhartless]

I know it's not in your original post, but I have used 139 grain Hornady BTSP in my 7 mag for years and puts everything lights out.

What powder are you using with the Eld-X?
